Thompson now works for Fox Sports in the US after a spell on the Sky Sports F1 channel last season – and is perhaps best known for going out with one half of Ant and Dec.

She has been in a relationship with Olympic hero Ainslie since April.

Ainslie has a £650,000 home in Lymington, Hampshire, although he has recently been living in San Francisco to compete in the America's Cup.

Ainslie, who has won four gold medals and one silver over five Olympic Games, was previously with Dutch sailor Marit Bouwmeester, 25.

She won a silver in last summer’s Olympics at Weymouth on the same day as Ainslie won his latest gold.

Privately educated Miss Thompson, is the former girlfriend of ITV star Declan Donnelly, one half of Geordie duo Ant and Dec.

They split in 2011 after two years, with his apparent lack of decisiveness about their future together reportedly the issue, although she insists ‘there’s no animosity between us’.

She has known Ainslie for three years and in an interview with this Saturday’s forthcoming issue of the Daily Mail’s Weekend magazine, Miss Thompson said: ‘We met through friends at an event – and I don’t really know how to describe it.

‘It was a bit of a thunderbolt moment but a thunderbolt that took years before it became anything real. We were in different places but then in April the stars aligned and it made sense to be together, and we haven’t looked back since. It’s very special – he makes me very happy.’

Now Ainslie's America’s Cup stint is over, Miss Thompson says they will be able to spend more time together – although last week he flew back to Britain.

In a recent interview, he hinted that a family may soon be on the cards. ‘I better sort that out at some stage soon,’ he said.
